SSM框架介紹

SPRing框架介紹

Spring是一個開源框架，Spring是于2003 年興起的一個輕量級的java 開發框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中闡述的部分理念和原型衍生而來。它是為了解決企業應用開發的復雜性而創建的。Spring使用基本的JavaBean來完成以前只可能由EJB完成的事情。然而，Spring的用途不僅限于服務器端的開發。從簡單性、可測試性和松耦合的角度而言，任何Java應用都可以從Spring中受益。簡單來說，Spring是一個輕量級的控制反轉（IoC）和面向切面（AOP）的容器框架。

Spring Mvc框架介紹

Spring MVC屬于SpringFrameWork的后續產品，已經融合在Spring Web Flow里面。Spring MVC 分離了控制器、模型對象、分派器以及處理程序對象的角色，這種分離讓它們更容易進行定制。

Mybatis框架介紹

MyBatis 本是apache的一個開源項目iBatis, 2010年這個項目由apache software foundation 遷移到了google code，并且改名為MyBatis 。MyBatis是一個基于Java的持久層框架。iBATIS提供的持久層框架包括SQL Maps和Data access Objects（DAO）MyBatis 消除了幾乎所有的JDBC代碼和參數的手工設置以及結果集的檢索。MyBatis 使用簡單的 xml或注解用于配置和原始映射，將接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java對象）映射成數據庫中的記錄。

項目實踐

使用maven進行項目構建
